ok now i have a new vibration and its not just my tolerance w/ford dealerships about to snap. (at a stop/gradual accelerating to make a left 45deg.angle /(vibration of whole cab! not steering wheel) and it almost seems like loss of track in back. and also front tires are pretty rough on outer edges. and also tire wear is more than normal 21,000 on 04 ,compared to spare (contental's stock) please send some 411 maybe this might help other vib. on high way?
